Adding warnings and notices to load_wsdl()

I have begun hacking at the 5.3 branch of the code in an attempt to create a patch for 50698. I'd like to employ the "debug by printf()" method of development. However, it seems that all the warning/notices I generate inside the load_wsdl() function do not get displayed. I know its not a config error because a call to trigger_error() will display a notice. So how do I either get php notices/warning to display inside of that function, or get debug into via some other method? Example of how I am trying to add debug info: Index: php_sdl.c =================================================================== --- php_sdl.c (revision 293642) +++ php_sdl.c (working copy) @@ -699,6 +699,9 @@ sdlCtx ctx; int i,n; + /* Debug information */ + soap_error1(E_NOTICE, "PHP-SOAP Using uri of '%s'", struri); + memset(&ctx,0,sizeof(ctx)); ctx.sdl = emalloc(sizeof(sdl)); memset(ctx.sdl, 0, sizeof(sdl)); @@ -834,9 +837,9 @@ } else { soap_error1(E_ERROR, "Parsing WSDL: PHP-SOAP doesn't support transport '%s'", tmp->children->content); } + tmpbinding->bindingAttributes = (void *)soapBinding; } } - tmpbinding->bindingAttributes = (void *)soapBinding; } name = get_attribute(binding->properties, "name");
